Article Title: Enhancement of Astroglial Aerobic Glycolysis by Extracellular Lactate-Mediated Increase in cAMP

doi: 10.3389/fnmol.2018.00148

Figure Lengend Snippet: Inhibition of AC reduces the L -lactate- and 3Cl-5OH-BA-induced increase in [cAMP] i and [lactate] i (A,B , panels i) Mean time-courses of FRET ratio signal changes normalized to the maximum signal change for (A,i) Epac1-camps upon addition of 20 mM L -lactate and (B,i) Laconic upon addition of 0.5 mM 3Cl-5OH-BA (black lines) in the absence (white circles) and presence (black circles) of 100 μM DDA, an inhibitor of AC. Each data point represents mean ± s.e.m. ( A,B , panels ii) Mean relative changes in FRET ratio (Rel. ΔFRET ratio) upon L -lactate (A) and (B) 3Cl-5OH-BA stimulation in the absence and presence of DDA. Relative ΔFRET values (%) were calculated by dividing individual ΔFRET values with the average ΔFRET value upon L -lactate or 3Cl-5OH-BA stimulation. Note that the inhibition of AC by DDA causes ∼50 % reduction in L -lactate-induced increase in [cAMP] i in astrocytes and a ∼30–60% reduction in 3Cl-5OH-BA-induced increase in [lactate] i in astrocytes, 3T3-L1 and BT474 cells. In BT474 cells the application of 3Cl-5OH-BA initiated a transient reduction in [lactate] i that was diminished in the presence of DDA. Numbers adjacent to black bars represent number of cells. Data are in the format of the mean ± s.e.m ( ∗ P < 0.05, ∗∗ P < 0.01, ∗∗∗ P < 0.001). Data for every set of experiment was acquired from at least two different animals.

doi: 10.1093/nar/gkz1151

Figure Lengend Snippet: Figure 1. Local RNA in situ hybridization. (A) Schematic overview of a microfluidic implementation of chromogenic RNA in situ hybridization. The initial preparation of the tissue section including paraffin removal (1), heat (2) and protease (3) pretreatment, as well as fixation was performed globally. The primary probe was then hybridized locally to the RNA of interest (4). In this case the detection of HER2 is shown with internal negative (dapB) and positive (ActB) controls. Finally, the amplification of the signal using preamplifier and amplifier strands (5), the binding of enzyme (6), and the enzymatic reactions (7) were performed globally on the whole slide. (B) Fluorescence images of RNA-ISH experiments detecting the gene expression of HER2 in cell pellet sections of the breast cancer cell lines MCF7 (left), SKBR3 (center) and BT474 (right). Probes directed against bacterial dapB and ActB were used as negative and positive controls, respectively. Scale bar: 100 m.

Article Title: Merlin deficiency alters the redox management program in breast cancer

doi: 10.1002/1878-0261.12896

Figure Lengend Snippet: Merlin‐deficient breast cancer cells display a dysfunctional antioxidant system. Expression levels of GCLC and GCLM were decreased in MCF7 KD (A and B, respectively) ( P < 0.0001 and P = 0.0029, respectively) and T47D KD (C and D, respectively) ( P = 0.0001 and P < 0.0001, respectively) compared to their NT controls. In contrast, expression levels of GCLC and GCLM were increased in SUM159 Merlin (E and F, respectively) ( P = 0.0071 and P = 0.0027, respectively) compared to SUM159 VEC. Nrf2 activity was measured by an NQO1‐driven Nrf2 luciferase assay which showed decreased activity in MCF7 KD (G) ( P = 0.0111) and T47D KD (H) ( P = 0.0001) compared to their respective NT controls; Nrf2 activity was increased in (I) SUM159 Merlin ( P = 0.0095) compared to SUM159 VEC ( n = 3 for each group). (J) Protein levels of Nrf2 were decreased while Keap1 increased in Merlin‐deficient cells compared to controls; the opposite was seen in the comparison between SUM159 Merlin and SUM159 VEC ( n = 3 for each group). (K) SOD1 protein expression is decreased in NF2 ‐silenced breast cancer cells, MCF7 KD, T47D KD, and BT474 KD compared to their non‐target (NT) controls. In contrast, SOD1 is upregulated in SUM159 Merlin compared to SUM159 VEC. Error bars represent ± SEM. Student's t ‐test was applied for statistical analysis. Band densitometry of immunoblotting is shown. β‐actin was used as loading control.
